sora 2 Prompt: Use the uploaded image as the exact starting frame. Keep the same baby, face, hairstyle, clothes, high chair, kitchen, table, lighting, camera angle and composition. Do not change the environment. The baby is holding a small lemon slice with both hands. During the entire 5-second video, the baby naturally brings the lemon slice to his mouth and takes one clear bite. 0–2 seconds: The baby raises the lemon slice toward his mouth and takes a small bite. 2–3 seconds: The baby chews the lemon and realizes the sour taste. 3–5 seconds: The baby makes a very strong, funny sour-face reaction: eyes squeeze shut, eyebrows scrunch, nose wrinkles slightly, lips pucker, cheeks tighten, and his face clearly shows that the lemon is extremely sour. He remains seated safely in the high chair. The reaction should be cute, funny and realistic, with natural baby facial expressions and subtle head movement. IMPORTANT: The baby must actually bite the lemon. Do not simply hold the lemon near the mouth. The bite must be clearly visible. The baby must visibly react to the sour taste immediately afterward. Photorealistic, natural movement, realistic baby facial expressions, cinematic warm kitchen lighting, smooth motion, 5 seconds, portrait 9:16.
